Abstract

A static dissipative laminate consistently having an internal resistance less than 2 x 10<6> and a resistance to ground measurement of about 5 x 10<6> and a surface resistance in the static dissipative range even at a very low humidities is produced by the use of an ionic salt and an humectant in the overlay and further by the use of a special top core sheet containing 0.6-1.0% by weight of carbon fibers. <IMAGE>
